3D High-Definition Laser Surveying

Utilizing Terrestrial Laser Scanning technology CenterGeo is able to capture high-density 3D geospatial data of complex structures and sites. The technology creates accurate three-dimensional images of real-world objects and existing conditions. A laser scanner records millions of highly accurate, unique points by sweeping its beam over a surrounding scene or object. The scanners X,Y,Z measurements are recorded and displayed as a "point cloud" which can be viewed, measured and navigated as a 3D model providing a snaphot in time and incredible insight to the scene.

The high-density accurate data, speed of data capture, the safety and convenience of remote acquisition and measurement, 3D visualization and digital imagery are the distinguishing features of laser scanning that provide the greatest benefits. Abundance of data captured in laser scanning reduces questionable data, provides over sampling to ensure accuracy and that all objects, structures, geometry are captured. High point density data ensures a complete topographic survey: All details are captured and all data captured are direct measurements. Imagery and 3D visualization provides added confidence that mapped objects correspond to actual existing conditions.

The benefits of the laser scanning technology for the project are following:

  • Allows detailed measurement of ALL data, including small details that may be important in later reconstruction.
  • 3D geometry of any object will be complete, highly detail and accurate.
  • Eliminates need to return to site for inspection or "one more measurement".
  • Collect data in areas not accessible.
  • Quick and safe data acquisition will minimize intrusion on the object.
  • Allows for 3D visualizations if required.
  • Historic preservation of its architectural heritage.
     

Acquired scanned data can be modeled in 3D or converted to 2D drawings (plan view, elevation cross section, and topography) for export to any standard CADD platform.  Scanned information is linked together to form a comprehensive digital image.

 

Applications of the laser scanning technology include:

  • Topographic mapping.
  • Architectural and Engineering As-built Surveys.
  • Civil traffic and utility planning.
  • Historic preservation and archives.
  • Structural steel mapping and cataloging.
  • Conceptual design and interference checking.
  • Fabrication and construction inspection.
  • Manufacturing and reverse engineering.
  • Accessibility renovations.
  • As-built surveys for plant facilities including offshore oil and gas platforms.
